In addition, the expression of GALNT2 was also upregulated in various cancer types, such as breast invasive carcinoma (BRCA), colon adenocarcinoma (COAD), head-neck squamous cell carcinoma (HNSC), kidney renal clear cell carcinoma (KIRC), lung adenocarcinoma (LUAD), lung squamous cell carcinoma (LUSC) and stomach adenocarcinoma (STAD) (Supplementary Figure S1D). This evidence concerns the gene GALNT2 and gastric adenocarcinoma.
